Warriors' David Lee (hip) out for season

David Lee will miss the rest of the 2013 playoffs after completely tearing his right hip flexor during Game 1 of the Warriors' first-round series with the Nuggets on Saturday.

The Warriors announced that an MRI on Sunday revealed the extent of the injury, which the Warriors initially called a "probable right hip flexor strain" on Saturday. Lee underwent X-rays on Saturday, which were negative. CBSSports.com reported and USA Today Sports first reported the diagnosis.

Lee appeared to suffer the injury on a drive to the hoop that ended with him absorbing contact from JaVale McGee and falling awkwardly to the court early in the fourth quarter. After attempting his free throws, Lee doubled over in pain and immediately departed the court, favoring his right hip area. He finished with 10 points (on four-for-14 shooting) and 14 rebounds in 29 minutes.

Lee, 29, averaged 18.5 points and 11.2 rebounds per game this season, making him Golden State's second-leading scorer and leading rebounder. He was selected to his second All-Star Game this season. Saturday marked the first playoff game of his eight-year career.

Denver, the No. 3 seed, now holds a 1-0 series lead over Golden State, the No. 6 seed. The Warriors are making their first postseason appearance since 2007. Game 2 is set for Tuesday night at the Pepsi Center.
